Last Saturday night, a Model X drove through a guardrail in Montana, reportedly also with Autopilot engaged.
Fortunately, both the driver and the and other passenger are alright, according to Electrek. A friend of the driver’s posted pictures of the crash and details of the incident on the Tesla Motors Club forum afterwards:
Both 2 people in the car survived. It was late at night, Autopilot did not detect a wood stake on the road, hit more than 20 wood stakes, tire on front passenger side and lights flew away. The speed limit is 55, he was driving 60 on autopilot. His car is completely destroyed. The place he had the accident does not have cellphone signal, it is 100 miles from the hotel.
Just got more photos from the driver. The car was in autopilot at speeds between 56-60, the car drove off the road hit the guard rail wood posts. I questioned him how can AP drove off the road himself, he said he also want to find out.
Additionally, the photos show a road that lacks a center divider, though the v7.1 software update tweaked the Autopilot system to allow the Tesla to travel down roads without a center divider at restricted speeds.
Jalopnik has reached out to Tesla for a comment on the matter, and will update this post as we learn more.
